The Roots drummer was on hand for the ceremony and reception, where he served as the DJ and (unofficial) photographer. Posting various snapshots to his Instagram account with the hashtag #weddinginthewoods, Questlove showed off everything from the bride's arrival (by canoe) in a mustard-hued gown, to the guests, to the cake-cutting and dancing.

It was a non-traditional ceremony for the newlyweds, with Cross, 48, donning a sweater vest and white button-down shirt for the party. At the ceremony, he added a jacket, bow tie and boutonniere.

Tamblyn, 29, flaunted her curves in a lace, figure-hugging yellow dress with a plunging neckline. On her feet, she went bare.

The Sisterhood of the Traveling Pants reunited for the occasion, with Alexis Bledel, America Ferrera and fellow newlywed Blake Lively -- who was accompanied by her beau, Ryan Reynolds -- all in attendance. Also on the guest list were Amy Poehler, Kristen Schaal and Jason Ritter.
